Description

I am trying to add files into class path using:
DistributedCache.addFileToClassPath

If file path is relative path like: /user/dir1/dir2/a.jar everything is ok means if I try to get these files from the
class path using DistributedCache.getFileClassPaths it returns me the path correctly.

However if I use path like hdfs://nn:7877/user/dir1/dir2/a.jar
And try to get class path files using DistributedCache.getFileClassPaths
it returns me 3 files like:

hdfs
//nn
7877/user/dir1/dir2/a.jar
